1. A catheter system for delivering an aerosol to a patient comprising:
a catheter shaft having a proximal end and a distal end, the distal end for insertion into the patient, wherein the distal end comprises a j-shape;
a gas lumen extending through the catheter shaft, the gas lumen defining a distal gas orifice in communication with the gas lumen, the distal gas orifice located at the distal end of said catheter shaft;
a liquid lumen extending along at least a portion of the catheter shaft, the liquid lumen defining a distal liquid orifice in communication with the liquid lumen, the distal liquid orifice located at the distal end of said catheter shaft; and
wherein the distal gas orifice and the distal liquid orifice are aligned to nebulize a liquid in a direction toward the proximal end of the catheter shaft, wherein the liquid comprises a medicine.
